perf(docs): Disable GH checks on docs that don't apply to docs

[J2-D2-3PO]

Description

https://wandb.atlassian.net/browse/DOCS-1108

Proposes disabling GH action checks that don't apply to things that live in the docs folder.

Reason:

1. Save 💰 and resources
2. Speed up docs deployment / PR process. As of now, every docs PR has to pass 100+ checks, most of which don't apply to the docs themselves
3. Free up engineering from having to help docs team figure out some of the issues with tests randomly failing that don't apply anyways

Testing

• Push changes to docs to test what happens on this branch
• Need to confirm with the team that all changes are ok first. Assuming that we only need to keep the following tests for docs (but if we can disable more then cheers )
  • weave/.github/workflows/check-which-tests-to-run.yaml
  • weave/.github/workflows/cla.yaml
  • weave/.github/workflows/deploy.yaml
  • weave/.github/workflows/pr.yaml
  • weave/.github/workflows/release.yaml
  • trace-docs in weave/.github/workflows/test.yaml
    I added this to trace-docs to override the global docs disable on this test: if: ${{ github.event_name == 'push' && (github.event.before == 'docs/**' || github.event.commits | contains('docs')) }}. Alternatively, could break out into separate file, but need to check with team if this would cause other issues / more work

@wandb/weave-team could I get someone to look at this before I proceed any further?

For one, I'm not sure what's going on here.
